...EH Glaessgen; IS Raju; CC Poe, Jr An analysis based on plate finite elements, nonlinear spring elements and the virtual crack closure technique has been implemented to study the effect of stitching on strain energy release rates for debond configurations. The stitches were modeled as discrete...

... rate. To evaluate the utility of these results for the analysis of a more realistic geometry, independent fatigue tests of a boron-epoxy doubler bonded to a cracked aluminum sheet were also examined. No debonding of the doubler occurred during 300 000 cycles. A finite element analysis...

..., there is no clear consensus on how to interpret the data and quantify the interfacial properties. In this paper, the fiber fragmentation test is modeled with the objective of studying the effect of interfacial bond strength and post-debonding frictional effects on the progress of the fragmentation process. The load...

...S Subramanian; KL Reifsnider; WW Stinchcomb A micromechanics model has been developed to predict the tensile strength of unidirectional composites. The local stresses are calculated using shear lag analysis, including the effects of interfacial debonding. The tensile strength of the composite...

...WS Johnson; S Mall An experimental study of cracked-lap-shear specimens was conducted to determine the influence of adherend stacking sequence on debond initiation and damage growth in a composite-to-composite bonded joint. Specimens consisted of quasi-isotropic graphite/epoxy adherends bonded...
